When developing mechatronic systems, it is necessary to consider mechanical components and their design. Knowledge of design methodology and structural components (machine elements) is essential for this. On the basis of strength theory and the representation of technical products, connecting elements, elements of rotary motion and elements for the transmission of rotary motion can be calculated and integrated into an overall design. After successfully completing the module, students will be able to dimension, design, select and integrate machine elements in a mechatronic environment. Students are familiar with the fundamentals of methodical design systems and are thus able to help shape the interface to constructive mechanical engineering in development projects.

1. Basics -> product development process, design concept, types of design
2. Design system -> design methodology, concept development, solution search
3. Representation of technical products -> component and assembly representation, tolerances, fits
4. Component dimensioning -> types of stress, fatigue strength
5. Connecting elements and mechanisms in mechatronic systems -> structure, selection and design of screw connections and shaft-hub connections
6. Elements of mechanical power transmission in mechatronic systems -> Functionality and calculation of shafts, roller bearings and gearboxes

The total workload for the module is 150 hours (see also "ECTS credit points and grading").

• Written examination or
• Portfolio exam

The lecturer determines the type of assessment: written examination or portfolio assessment.

The portfolio assessment consists of two elements that focus on the methodological and computational skills taught. It comprises an oral project report (PMU) throughout the semester and a final examination at the end of the semester (K1). The total number of points is 100, of which a maximum of 40 points can be achieved through the oral project report and a maximum of 60 points through the one-hour written examination. 

The following information regarding duration applies to the types of examination permitted in the module:
Written examination: see the applicable study regulations
Oral project report (as part of a portfolio examination): 15–20 minutes

The module requires basic knowledge of mechatronics and an understanding of mechatronic systems. With regard to mechanical engineering-related design calculations, prior knowledge in the disciplines of statics, strength of materials and materials engineering is important.

Upon completion of the module, students will be familiar with the fundamentals of methodical design and the functioning of selected machine elements. They will be able to classify the design of mechanical components in the development of mechatronic systems. Furthermore, they will be able to describe the procedure for designing components and assemblies and explain the necessary mathematical design.

After successfully completing this module, students will be able to confidently apply and justify the methods taught for the conception and evaluation of a constructive design, as well as for the requirement-based design, calculation and selection of machine elements in the development of mechatronic systems.
